## Narrative

An employee was using a pneumatic wrench to tighten a spring cap onto a bolt while repairing a metal shearing machine. As the employee added downward pressure on the spring, the bolt snapped, releasing the spring's compression and causing it to shoot out of containment and into the employee's forehead. The employee sustained a forehead laceration that required stitches and a minor skull fracture.
